1-Diazidocarbamoyl-5-azidotetrazole, often jokingly referred to as azidoazide azide,[5] is a heterocyclic inorganic compound with the formula C2N14.

1-Diazidocarbamoyl-5-azidotetrazole was produced by diazotizing triaminoguanidinium chloride with sodium nitrite in ultra-purified water.

[6] Another synthesis uses a metathesis reaction between isocyanogen tetrabromide in acetone and aqueous sodium azide.

This ring form is in equilibrium with isocyanogen tetraazide, an isomeric acyclic structure that has long been known to cyclize quickly to the tetrazole.

This instability makes many such compounds liable to explosive decomposition, releasing nitrogen gas.
